A solvent extraction circuit for uranium is to be designed using the equilibrium loading data at pH1.5 from shake-out test results using Alamine 336 dissolved in a diluent plotted in the figure shown below. (a) A leach liquor containing 0.55g/L uranium is to be treated at a flowrate of 100 m3/h. Construct a McCabe Thiele diagram to answer the following questions. (i) Draw the operating line needed to determine number of stages required to extract 90% of uranium using Alamine 336 at an organic flow rate of 20m3/h. The stage efficiency is 90%. (ii) Determine the required number of stages, which satisfies the conditions in (i). [10 marks] (b) What is the concentration of uranium in the loaded organic phase? [5 marks] (c) The loaded uranium is stripped with an ammonium sulfate solution at an organic/aqueous flow rate ratio of 3.5/1. Calculate the percentage of uranium stripped in a single stage assuming a distribution coefficient of 1.8. [10 marks]
